I am building a 914-6 and I have an issue where the battery does not charge. Basically everything is new on the car (alternator, voltage regulator, battery & cables). The car runs fine but just will not charge the battery. I have checked the grounds on the body and at the transmission. The belt seems fine and is new. I pulled the battery and the regulator and brought it to a shop where they said it was putting out 14.2V using my regulator.
My Alternator wires are as follows; Red from B+ to Starter Black from DF to DF on the Regulator Brown from D- to D- on Regulator Blue from D+ to D+ on Regulator and then to the Dash Battery Light. (which is on all of the time) Ground from D- to engine case. When I put the system back together, I checked the continuity of each cable to assure myself it wasn't just a pulled connector or broken wire. When the car is running and reved to 2,000 RPM I still only get battery voltage. Please help with any thoughts on what I should check next. Thanks. |

The alternator light in the instrument CANNOT be an LED; filament bulb as original only. LED will not allow charging system to work!
